[gentoo-user] udev downgrade

[gentoo-user] udev downgrade

[James]

The thread "Ethernet Machinations"
is finished and all ethernet issues
are resolved.


I'm starting a new thread as to deal with what to
do about udev. The same system mentioned in
the previous ethernet thread had become upgraded to
udev-196-r1 (late one night when I was tired
AND NOT THINKING TOO WELL...............
I have since been on a roller_coaster ride with
udev, almost eudev and version dev experimentations
as an accident...........

From the last thread:
I don't know what version of udev you're running (sorry if I missed it,)
but the udev-186 elog says:
        "Upstream has removed the persistent-net and persistent-cd rules
         generator. If you need persistent names for these devices,
         place udev rules for them in /etc/udev/rules.d."



I just sync and I have only have these versions of udev:
 Available versions:  ~141-r1 ~146-r1^t ~149 ~151-r4 ~164-r2 171-r9 ~195^t
~196-r1^t **999


So unless somebody can give me good reason, I'm downgrading to
udev-171 asap on this (only) system running udev 196.......
(ps, I like to experiment, but not with udev et. al.)


I even thinking or running 'emerge -e system' just to ensure
nothing is missed?

Suggestions are most welcome.

Long night, when you have to answer your own posts.....

Now I get:


emerge -p1u udev

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     UD ] sys-fs/udev-171-r9 [196-r1] USE="rule_generator%*

[blocks B      ] <sys-fs/udev-186 ("<sys-fs/udev-186" is blocking
sys-fs/udev-init-scripts-17-r1)

!!! Multiple package instances within a single package slot have been pulled

  (sys-fs/udev-196-r1::gentoo, installed) pulled in by

(sys-fs/udev-171-r9::gentoo, ebuild scheduled for merge) pulled in by
    (no parents that aren't satisfied by other packages in this slot)


ideas?

Too late, too tired, but do you have:

>=sys-fs/udev-181

in /etc/portage/package.mask ?

The problem is you are trying to downgrade sys-fs/udev but not 
virtual/udev. If you want to force using udev-171, you need to mask both 
the real and virtual atoms. Try this in /etc/portage/package.mask/udev:

 >=sys-fs/udev-181
 >=virtual/udev-181

Then emerge -avuD1 udev and see if that fixes it.

Ehm... according to http://packages.gentoo.org/category/sys-fs?full_cat
udev-171-r9 is the only stable x86 version, and udev-181 doesn't exist
at all?!

-Matt (still using 171 because at emerge -u world, an update never appeared)

Maybe this is true for a downgrade, but not normally:

mingdao@workstation ~ $ eshowkw udev

And, yes, this udev mask is used on 8 Gentoo boxen on this LAN.

I get the downgrades you would expect:



 UD ] virtual/udev-171 [196]
UD ] sys-fs/udev-171-r9

I also get some weird companion downgrades:

and these:

Does anything when you are running unstable (~amd64) and then trying
to push it toward stable? That's always been difficult and dare I say
unsupported.

OK, I only run stable so I have no experience in this area however I
am wondering whether you tried to temporize to something like mdev
stable, and went from mdev stable to udev stable if the results might
be more predictable/less obscure?

Just a thought,
Mark

I don't have Qt installed anywhere, so I can't reproduce that problem. I 
also don't see that particular version of qt-script in the tree, so I 
can't be sure, but my guess is some Qt dep that you already have 
installed depends on a newer version of udev than you will be getting 
after the downgrade, thus requiring it to downgrade as well.

Yes, I expected something like that. In all likelihood, you'll need to 
completely remove sys-fs/udev and virtual/udev and then reinstall the 
older version. You'll probably want to do this in single user mode (i.e. 
`rc single`), so running programs don't crash suddenly. A reboot 
afterward is probably a good idea as well.

I'm not sure what would crash, if anything. It may very well be fine; I 
was just offering the suggestion just in case. If it were me doing it, 
I'd at least do it on a virtual console and not in an X11 terminal, in 
case your keyboard stops working (which seems unlikely, but I've learned 
that nothing is too crazy to expect when dealing with udev)

I'm interested in what may crash, do you mean after logging out and in
again etc.. I have started and stopped udev in the past during testing
without any apparent problems.
